CDVI K2 KRYPTO Bluetooth Mullion Proximity Card Reader

Deliver secure, modern access control at the door with the CDVI K2 KRYPTO Bluetooth Mullion Proximity Card Reader. Designed for commercial and institutional security deployments, this proximity reader combines mobile and card credentials into a single, tamper-resistant device to streamline day-to-day access and reduce administrative overhead. The K2 supports Bluetooth and NFC for KRYPTO Mobile-PASS and mobile onboarding, while reading Mifare and DESFire EV1/EV2 credentials to ensure broad interoperability.

Engineered for enterprise integration, the reader offers up to a 2" (5 cm) read range and uses OSDP-2 with a fully secure RS-485 connection to the ATRIUM A22K controller, delivering encrypted communications and centralized monitoring for security teams. Its compact mullion form factor makes it ideal for narrow frames and retrofit projects, and 12 VDC operation eases power planning on existing low-voltage systems.

Whether upgrading an access control system, strengthening surveillance and monitoring, or deploying mobile-first credentials, the CDVI K2 provides a secure, flexible solution. Contact us to specify the K2 for your next access control or security integration.
